If I didn’t know any better I’d never guess it was your birthday today as you don’t look a day older, let alone a year! Happy birthday, my beautiful cousin!
As your elder sibling, it’s my duty to boss you around and act as though you’re always bothering me but seeing as today is your special day I’ll give you a break!
Today is your special day so I won’t make it all about me, but as you turn another year older I can’t help but be reminded of the fact that I’m even older than that! Thanks a lot!
